  1. 31. Environmental pollutants and the reproductive system in birds : Developmental effects of estrogenic compounds

    Författare :Cecilia Berg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Avian embryo; test system; xeno-estrogen; endocrine disruption; reproductive organ differentiation; oviduct; testis; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; ekotoxikologi;

    Sammanfattning : A number of environmental pollutants have been shown to mimick the action of the female sex hormone estrogen and are, therefore, suspected to be responsible for reproductive abnormalities seen in wildlife. Test systems which can be used in hazard and risk assessment of chemicals with estrogenic effects are consequently needed. LÄS MER

  3. 32. Endogenous hormones in the etiology of ovarian and endometrial cancers

    Författare :Annekatrin Lukanova; Eva Lundin; Pär Stattin; Rudolf Kaaks; Susan E. Hankinson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Public health; ovarian cancer; endometrial cancer; sex-steroid hormones; sex-hormone binding globulin; insulin-like growth factor-I; insulin-like growth factor bidning proteins; C-peptide; Folkhälsomedicin; Public health medicine research areas; Folkhälsomedicinska forskningsområden; epidemiologi; Epidemiology;

    Sammanfattning : The main purpose of this thesis was to examine the relationship of pre-diagnostic circulating levels of sex-steroids (androgens and estrogens), sex hormone binding globuline (SHBG), insulin-like growth factor-I (IGF-I), IGF binding proteins (BP) and C-peptide (as a marker of pancreatic insulin secretion) with risk of ovarian and endometrial cancer. Additionally, the interrelationships of body mass index (BMI), sex-steroids, IGF-I and IGFBP-3 were examined. LÄS MER

  4. 33. Estrogen receptor gene activity within the brain and the relation to psychiatric disorders : mapping and function

    Författare :Marie Österlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :steroid hormone; ER system; in situ hybridization; rnRNA; ER serotonin; depression; affective disorders;

    Sammanfattning : Estrogens have for a long time been known to regulate neuroendocrine functions in the central nervous system (CNS), primarily related to reproduction. In recent years estrogens have been found to also modulate many other brain functions, for example mood and cognition. LÄS MER

  5. 34. Ear and hearing problems in Turner syndrome

    Författare :Annika Elmqvist Stenberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Turner syndrome; tympanic membrane pathology; hearing loss; otitis media; estrogen receptors; presbyacusis; immunology; mouse; rat; human; cochlea; psychosocial; audiometric testing.;

    Sammanfattning : Turner Syndrome is a common chromosomal disorder and affects approximately one in every 2000 newborn girl. The syndrome is defined as a total (45,X) or partial loss of the second sex chromosome in combination with the typical characteristic features, which are short stature (less than 150 cm), absent estrogen production due to ovarian dysgenesis, with failure to enter puberty spontaneously and infertility.

  7. 35. Vasomotor symptoms in postmenopausal women : the role of acupuncture and calcitonin gene-related peptide

    Författare :Yvonne Wyon; Britt-Marie Landgren; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : A majority of postmenopausal women experience vasomotor symptoms, which have a significant impact on the women's quality of life. Estrogens are the treatment of choice but can for different reasons not be used by all women. There is therefore a great need for viable alternative treatments. LÄS MER
